Is this something I need to worry about?

dev.cerbos.sdk.CerbosException: RPC exception [Status{code=DEADLINE_EXCEEDED, description=deadline exceeded after 0.820751800s. Name resolution delay 0.007160300 seconds.

Sounds like the client can't connect to Cerbos. Is the service up?

Seems to be up, at least when looking at docker containers

Is port 3593 exposed to the host? That's the port used by the SDK.

Yes,

$ docker ps -a

Interesting... it should be fine then. You could try increasing the timeout in the client builder to see if that makes a difference. There's a

WithTimeout

option for that.

That did the trick. I added a 1s timeout and was able to check access

{create=false, view:public=false}
